BACKGROUND

There are many scenarios in which a large area must be efficiently and effectively disinfected within a short period of time. Containment protocols for managing biological substances may require prompt disinfection of an area after a breach or outbreak of a biological substance from a controlled setting. Existing approaches to disinfect areas may not be suitably efficient or effective.

Accordingly, there is a need for improved handheld devices and systems for effectively spraying an area with a composition, such as a disinfectant composition. The present invention addresses this unmet need.

SUMMARY

In general, the disclosure provides improved handheld blower devices having improved heatable fan blade components which may be modularly or integrally installed therein. The handheld blower device is configured for improved performance compared to previous iterations and provides more effective coverage of an area with a solution sprayed therefrom. The heatable fan blade components may improve operation of the handheld blower devices by heating an air column within the device, heating the solution, and/or heating an aerosolized form of the solution prior to ejection from a spray nozzle of the device. An improved handheld blower device (e.g., a Mini-E™ device as provided by Advanced Non-Lethal Technologies Inc. of North Carolina, United States) may include a handheld axial air blower capable of spraying a plurality of liquid-coatings, e.g., disinfectant compositions, to cover large areas with speed and efficiency. The device includes spray nozzles, positioned at a top and a bottom of the device, configured to deliver the solution as a fine mist or aerosol that is directed and controlled by the axial air blower. With the combination of the axial air blower and spray nozzles, an operator assumes full command, ensuring improved surface coverage.

In one aspect, the disclosure provides a heatable fan blade component for a handheld blower device, the heatable fan blade component comprising a fan blade having a resistor puck disposed within a cavity of the fan blade. When a current passes through the resistor puck, the resistor puck and the cavity are heated.

Handheld Blower Devices, Systems, and Components

A function of any blower is creating and maintaining a stable thrust vector of the air-flow direction, velocity, and range. For this function in tandem with a variable speed controller creates an advantage giving the user variable coating control of the chosen coating location(s).

Heating elements operate through inducing electrical charge/electrons directly into a resistor structure, of which are mainly comprised of a metal or a metal alloy. As the electrons flow or propagate through the resistor's dense atomic structure, this in turn slows the electrical flow, constituting in a buildup of heat. In turn, an increase of this electrical-flow/input of the electrons constitutes a greater convection of the heat/heat-index. Certain appliances which comprise of an air conditioning system include hair dryers and countertop cooking appliances, and air fryers. These and similar devices communicate air that passes over a surface of a heating element and thereby heat and/or condition the local air column. Other examples include a hot plate used in cooking and a coffee brewer which includes a single snaked or wound resistor. In implementations of the present disclosure, a brushless DC (BLDC) motor may be used to heat a modular fan blade system through magnetic induction.

Mini-E: Superior Handheld Blowing

The axial blower fan creates a thrust vector, substantiating air direction and velocity. This function creates an advantage as it gives the operator control over direction and velocity, equaling greater coating control of the location(s). The axial blower includes an electronic variable speed control, such that a variable modulation of the blower speed may be achieved through use of a trigger, which allows for a user to adjust speed on the fly. A particular feature is a selector dial for selection of a desired speed. Axial is with the reference to the direction, same as a vector potential, the speed and direction of the flow. In essence, variable speed control is managed by an E.S.C/electronic speed controller which in turn manages the flow of electrons in a circuit. Pressure travel, whereby travel is the movement of the trigger by the finger force of the user which equals air speed, such that light pressure=slower flow of the electrons, and heavy pressure=faster flow of the electrons.

The diffuser or air flow stabilizer helps maintain a laminar flow from the axial blower fan. Laminar refers to a coherent flow of the air through a venturi or tapered constriction. The body of the Mini-E™ functions as the main venturi, while the diffuser maintains a coherent air flow. Blower fans chop the air, creating buffer zones or gaps in the airflow. In a sense the diffuser works as a set of mini wings making the airflow smoother.

The thrust vectoring diffuser contributes to the velocity and air speed with the specifications by the magnitude and direction of the flow. Vectoring involves the pivoting or motion with the physical diffuser, which equals control direction with the airflow. This grants the user an advantage, because the diffuser can be positioned to concentrate airflow in a desired direction, voiding of any need to tilt, turn, or adjust the unit. This function can be controlled through analog or digital actuation. In a general sense, vectoring controls the angle of which the air is flowing from the main-stator or axial blower fan through the venturi/shell of the Mini-E, which then contacts the surface wings/slats of the diffuser which diverts the air in the desired direction, either up or down.

The trigger assembly includes a trigger which controls the variable speed of the axial blower fan. The chargeable battery pack permits power flow to the components of the system. The boost button boosts velocity of the motor with the axial blower fan creating more air force for the coating range.

Picatinny rails may be included which provide a mounting platform for the various features, such as the lights, meters, and readouts, and the unit can be mounted with the mobile platforms such as with a truck or a robot, which may be a requirement for operation in certain hazardous locations.

UV light may be included which is harmful to bacteria and viruses. UV light may function as a sentry for the pre-treatment of incoming air.

Spray nozzles may be included which function in the atomization of the liquids and solutions into fine mist. The user can control the liquid flow through the flow valves with these positions on the top and bottom of the unit, respective to that nozzle. Users can control which nozzle set to use through these flow valves, giving greater control over the coating location and control of the solution particulate size, surfaces varies, and the capability to control particulate size is an advantage, whereby coatings being used will conform with the layout, albeit cracks, holes, fractures rough and/or smooth surfaces, for a superior coating coverage. In the listing below is the various nozzle function of each embodiment:

Mini-E, QUAD: four micro-spray nozzles atomize liquids into fine-mist. Users can control these through the flow valves with these positions on the top and bottom of the unit, respective to that nozzle. Top and bottom nozzles can be outfitted for a desired particle size, based on the user's preference and/or job application.

Mini-E, DUAL: two spray nozzles atomize liquids into fine mist. Top nozzle creates a heavier flow with the aerosol while the bottom generates lighter flow. Users can control these through the flow valves with these positions on the top and bottom of the unit, respective to that nozzle. Graphics pads may be positioned on the left side of this embodiment and illustrate the flow pattern of each nozzle. Top pad shows light spray and bottom pad shows heavy spray. Users can control which nozzle set to use through these flow valves, giving greater control over the coating location. Top and bottom nozzles can be outfitted for desired particle sizes, based on the user's preference and/or job-application.

Mini-E, DUAL: Peristaltic/Meter-Mixing-System/On-Demand-Mixing-System includes two spray nozzles which atomize liquids into fine mist. Top nozzle creates a heavier flow with the aerosol while the bottom generates lighter flow. Users can control these through the flow valves with these positions on the top and bottom of the unit, respective to that nozzle. Graphics pads may be positioned on the left side of this embodiment and illustrate the flow pattern of each nozzle. Top pad shows light spray and bottom pad shows heavy spray. Users can control which nozzle set to use through these flow valves, giving greater control over the coating location. Top and bottom nozzles can be outfitted for desired particle-sizes, based on the user's preference and/or job application.

A peristaltic pump creates positive placement or time release of the concentrate through a rotary motion/analog or by a digital signaling of a roller with which contacts with a flexible-tube, pinching said tube, creating a meter-flow of the concentrate. Peristaltic-mechanics can be fine-tuned to mix high-concentrate-disinfectant-compositions without the need to pre-mix. In addition, a mixing chamber may be positioned at a central location where the water and concentrate mix.

Referring now to FIG. 1A, there is depicted a front cross-sectional view of an exemplary heatable fan blade component in the form of a four-pole modular rotor (1400A). With reference to air-conditioning/heating mechanics of the device, for the heating of a local air column within the device, an induction interaction is generated between an alternating magnetic field generated by the stator (14-E of FIG. 1B) coil configuration (which acts as a transmission coil) and the receiver coil (14-D2). During this process, the alternating magnetic field of the stator transfers electrical current within the receiver coil (14-D2), which powers the oscillator circuit (14-D4) which regulates the electrical current through the receiver coil (14-D2). The electrical current passes through the receiver lead lines (14-D3) wound with the stator supports (14-D5) and resistor puck mounting braces (14-D6) connecting to the resistor pucks (14-D7). As current passes through the resistor pucks (14-D7) this in turn increases the heat index within the cavity of the fan blades (14-D), whereby the rotation of the rotor (14-D10) and fan blades (14-D) heats the local air column and in turn the rotation acts as a heat sink for the fan blades (14-D).

Referring now to FIG. 1B, 1400B there is depicted a front cross-sectional view of the four-pole modular rotor which includes a non-conductive material with seven symmetrically spaced fan blades. Mounted within the rotor are four permanent magnets that are symmetrically spaced and of different dipolar-configurations (Permanent-Magnet-A=North, Permanent-Magnet-B=South, Permanent-Magnet-A=North, Permanent-Magnet-B=South), which interact with the stator to create rotation. In various implementations, a BLDC motor is used in devices and systems of the present disclosure. A six-pole stator (14-E) is shown which includes a circular disk constructed of a non-conductive material with six symmetrically-spaced stator support columns (14-E1) extruded along the edge of the disk, in which filaments (14-E2) are wound with the stator support columns (14-E1) in a specific direction, creating a magnetic north pole/START-1 and connecting by a lead-filament (14-E3) wound in the opposite direction to an adjacent stator support column (14-E1) to create a magnetic south pole/END-1 of which equates to a coil or COIL-1. This winding process is repeated with each stator support column (14-E1) of which START-2/NORTH to END-2/SOUTH=COIL-2, START-3/NORTH to END-3/SOUTH=COIL-3 to create a three-phase motor configuration. The totality of these windings creates a coil configuration. For the streaming of the direct current through a coil, which energizes that coil and creates an electromagnet/magnetic field. Through the alternation of these magnetic states in each coil by a Hall sensor (14-E4) on a bread board (14-E5) this creates a simple force mechanic of the potentials between the permanent magnets (14-D8) of the rotor (14-D10) and with the stator (14-E) this creates rotation of the rotor (14-D10). Revolutions of the rotor (14-D10) at slower speeds are tracked with better efficiency by the speed sensor strip (14-D6) through the magnetic field from Is the permanent magnets (14-D8).

For this conceptualization of the fan rotor (5), external features include the LED sheath (6) and integrated low-profile coupling hub (3).

Referring now to FIG. 3 , there is depicted a side view of a swapping of the modular heatable fan blade (100) with a finger-gripping of a quick-connect coupling and performing an upward motion with the quick-connect coupling, which actuates tension spring(s) and frees the heatable fan blade from a low-profile coupling hub. The swapping of the modular heatable fan blade (100) may be performed with a finger gripping of the quick-connect coupling (2) and performing an upward-motion with the quick-connect coupling (2) which actuates the tension springs (2A of FIG. 5 ) and in the tandem recesses the detent balls (2B of FIG. 5 ), thereby freeing the modular heatable fan blade from the low-profile coupling hub (3). For this implementation of the rotor (5) there is shown external features which include an LED sheath (6) and integrated low profile coupling hub (3). For this implementation, these closures is with a single coupling method, but in alternate implementations, may use a twist-lock/coupling, a pin-lock/coupling, a magnetic coupling, a threaded fastening, a form-fit, and/or a snap-fit.

Referring now to FIG. 3A and FIG. 4 , there is depicted a side view and a close-up perspective view of a separation of the modular heatable fan blade (100) from the rotor to reveal the low-profile coupling hub and external features of a female power transfer communication plate and a detent notch. The modular heatable fan blade (100) may be separated from the fan rotor (5) to uncover the low-profile coupling hub (3). The low-profile coupling hub (3) external features includes a female power transfer communication plate (3A) and detent notch (4).

Referring now to FIG. 5 , there is depicted a cross-section-view of the modular heatable fan blade (100) with closures of the internal structure and other components. The modular heatable fan blade is heated through an electrical resistive mechanic mechanism whereby electricity passes through a resistive material and the atomic structure of the material slows propagation of the electron flow, creating friction which results in heat. For the shown embodiment, the modular heatable fan blade is shown coupled with the low-profile coupling hub of the unit. In the shown embodiment, enclosures of the internal structure and components are shown. The modular heatable fan blades may be heated through an electrical resistive mechanic mechanism by which electricity passes through a resistive material and the atomic structure of the said material slows propagation with the electrons flow, creating friction which results in heat. For this embodiment, the modular heatable fan blade (100) is coupled with the low-profile coupling hub (3) of the unit. The modular heated fan blade (100) includes LED (1A), heat insulation (1B), resistor puck (1C), resistor mounting bracket (1D), LED power line (9), male power transfer communication plate (1E), quick connect coupling (2) tension springs (2A), and detent balls (2B). The low-profile coupling hub (3) includes detent notches (4), female power transfer communication plate (3A), and wire windings (7).

FIG. 11D depicts a cross-sectional view top view of an exemplary handheld blower device having two spray nozzles 1100 showing the numbered components. In one or more embodiments, the handheld blower device may have one or more spray nozzles. In one or more embodiments either or both of these exemplary handheld blower devices 600 and 1100 may incorporate one or more modular heatable fan blades (100) as disclosed or contemplated herein, and may be used in any method for spraying an area with a solution as disclosed or contemplated herein.

In various implementations, a Tactical Turbine Aerosol Generator™ (T.T.A.G. System™) is a handheld axial air blower capable of dispersing thick vapors of smoke, and filling or covering large and small locations with speed and efficiency. The T.T.A.G-System™ includes a fuel tank which may hold kerosene, a solution pump which siphons the solution from the two solution containers, which feed said solution through a series of solution lines, upon which exit system through a system of spray nozzles by which the atomized liquid communicates with the heat generated by the mini jet turbine, in turn changing the physical state of the atomized liquid into a vapor, and combination of this heat with the vector potential/velocity generated by the mini jet turbine pushes the air in the desired direction.

In various implementations, the Mini-E™ may include the primary function of the T.T.A.G™ in which both share the same or similar base component structures including an axial blower, a pump, a solution bottle, solution lines, and spray nozzles. The primary function is what separates each as a distinct form factor. The T.T.A.G™ is an aerosol generator, however, unlike the Mini-E which coats using liquid base compounds, the T.T.A.G.™ system uses the liquids to generate thick vapors and/or smoke through a heating of those atomized-liquids.

Aero-Sanitization

The Mini-E operates by generating the laminar flow with the axial blower fan and operates in concert with the UV light, as the vents lining the back sides of the units generate a vortex, drawing in the surrounding air and sanitizing the air as it passes through the UV light rays and passes, with the sterilant aerosol flow from the spray nozzles, back into the environment. Both outside air and air being drawn into the unit are sterilized simultaneously.

The vortex operates in tandem with the UV light and pre-treats incoming air as the sterilant solution particulates/aerosol bonds with any viruses/pathogens by its very design before contacting a surface.

In general, all viruses are coated with proteins and contain genetic material which can either be DNA or RNA. Since both nucleic acids have phosphodiester bonds, the genetic material provides a partial negative charge to the virus. The viral nucleic acid genomes are wrapped in proteins that can be neutral, negative, or positive in charge. Therefore, the net charge of a virus depends upon the cumulative charges of the genetic material and the protein.

The electrical “signatures” of the viruses were extrapolated from the results obtained as follows: when the virus particles are more polarizable than the suspension medium, the charge density at the internal aspect of the interface between the particles and the medium is greater than the charge density at the external aspect of the interface. Thus, the net induced dipole on the virus particle is aligned with the applied electric field.

Di polarity or the dipole is a factor in the quantification of a virus. Citing of those facts, use of the electrostatic unit in particular creates a positive/+charge=net-result>virus′−charge-density×EMF=1. In other words, the electrical field generated by the electrostatic unit is exponentially greater of the charge density with the virus, therefore the virus will polarize to match said EMF/electromagnetic field.

Robotic Mounting

In various implementations, an axial blower truss includes a robotic mounting function. Protruding from the left and right-sides of the Mini-E shell are a set of trusses. These trusses may be used along with primary functions of the device and used to facilitate mounting of the device with a robot or some other mobile-platform(s).

Thrust Vectoring

The velocity or air speed may be accomplished according to the disclosure by controlling the magnitude and direction of the airflow. The physical diffuser may be equally controlled and used to direct the airflow. This grants an advantage, whereby the diffuser can be positioned to concentrate airflow in a desired direction, avoiding any need to tilt, turn, or make any adjustments to the unit. This function can be controlled through analog or digital-spurring. In the general-sense, vectoring controls the angle of which the air is flowing from the main stator or axial blower fan through the venturi or shell of the Mini-E, which then contacts with the surface wings or slats of the diffuser, which diverts the air toward the desired direction, e.g., up or down.

System Timer

In various implementations, a system timer is included which functions as a time measurement mechanism and documentation of the operational period with the Mini-E™ This feature mints or documents or records the whole duration of use of the unit, including the operational time and solution use and further, operates as an odometer or meter for the pump component(s), thereby enabling monitoring and maintenance of the longevity and/or warranty of the device component(s).

Tethering Systems and Extended Operation Functions

In various implementations, belt clip solution bottles are included with the variants, of which embodiments include the 1 L through 2 L capacity bottles for the mid-range coatings and are included and secured in place by a nylon jacket. The backpack can manage large range coatings, using the 1-gal capacity of the bottle which may be used for a sterilant.

For the backpack and belt clip solution bottles, each connects to the Mini-E™ by a standard 4 mm line through a quick connection and meter valve is with a 4 mm line of which measures and controls the flow rate of the solution by the belt clip solution bottles and backpack peripherals. The advantages of this tether system include variable positions in which the Mini-E can hold, in particular upside-down, due to the solution containers not needing to be connected to the physical system (e.g., Mini-E).

Flushing Options

Water-Flush: If required to flush system, remove the solution bottle and fill with water, and connect back to unit for flushing.

Air-Flush: By attaching an air hose to the auxiliary valve of the solution pump, air will travel through the solution lines and spray nozzles clearing of any calcification by the sterilant.

Peristaltic Pump

The peristaltic pump creates positive placement or time release of the concentrate through a rotary motion or analog or by a digital signaling of a roller with which contacts with a flexible tube, pinching the tube, creating a meter flow of the concentrate.

Methods of Assembly and Use

SYSTEM POWER ON and COATING MECHANICS of the Mini-E, Mini-E Quad-Flow 600, and Mini-E Dual-Flow 1100:

-   -   1: Connect Battery Pack. Make sure battery is with a good charge         before use.     -   2: Fill Solution Bottle with the pertinent disinfectant         composition.     -   3: Connect the Solution Bottle to the back of the unit via a         Quick Connect/Quick Release system.     -   4: Select which Spray Nozzle to use by turning either top or         bottom Flow Valves.
